So originally, I was going to post that the "links" tab used by 10k users still says "2000" reputation, but only 3 people can actually vouch for that. And it turns out it's only on the Meta site; the parent site properly says 10,000 reputation. I did some extra digging, and our FAQ also has the old reputation limits.

According to Sam Saffron, the reputation requirements on the FAQ are now linked to the actual site privilege levels, instead of being static text. The Web Application Site's Meta FAQ has the correct levels, and the tools link still does say 2000, so I'm thinking it's not a simple error of the FAQ being not updated but that the Meta hasn't been updated.

I can't actually confirm, though. We don't have access to a separate privileges page for the Meta site.
